Yeah, it's a tough one. How much is too much? When are you drunk or stoned? And how do you know?
I had three spiced pumpkin ales, high alcohol content, this last Friday with my fish dinner and felt a bit guilty about it, like it was excessive ( they were tasty ). I was mumbling through the Rosary. I doubt it was a pleasing sight to God.
From now on I'm going to limit myself to two beers with food, or two glasses of wine, and not drink unless I'm eating. It's good to set rules, even if they are a bit overly strict. They keep you out of trouble.
Before I was Catholic I used to get those giant bottles of Belgian beer like Chimay that are about 12-15% alcohol and blitz myself. It would be easy to fall back into that habit. It would even be easy to give myself an excuse since all those gourmet beers are brewed by monks, supposedly. Vatican II monks now, but I assume the tradition goes back a lot farther than that.
Back then I was living an evil life, would drive drunk and do other bad things while drunk. Now if I drank a Chimay I'd just curl up and go to sleep. But numbing yourself into a stupor is hardly putting on the armor of God. Maybe there is something wrong with simply paying $10 or $11 for a bottle of beer.
I have never taken a drug. I've always been too protective of the old Gehirn. I remember my mom offering me anti-depressants when I used to be suicidally miserable and I'd even turn those down. No one messes with my brain! Instead I began to read Kierkegaard and Deleuze and Guattari and watch weird occult films and listen to occult music and messed it up more than any drug could have...
The question with marijuana is, CAN you smoke just a little? My understanding is that it is far more addictive than alcohol.
